The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring first to fig. 1, fig. 1 is a first structural schematic diagram of a washing apparatus of the present invention, which illustrates a structure of the washing apparatus that enables a liquid to circulate in a washing tub and a reservoir assembly. As shown in fig. 1, the washing machine of the present invention includes a washing tub 1 for containing laundry, a pulsator 2, and a door 3. The pulsator 2 is rotatably disposed in the washing tub 1, and the pulsator 2 includes at least one rib 211, so that the pulsator 2 can agitate laundry contained in the washing tub 1 and liquid for washing the laundry through the rib 211 while rotating, so that the laundry can be washed by mutual friction between the laundry and the tub wall/pulsator 2 of the washing tub 1. The door 3 is provided at a top end opening position of the washing tub 1, for closing/opening the washing tub 1. And the washing machine also comprises a liquid storage component 4 communicated with the washing barrel 1 and an air delivery component 5 hermetically connected with the liquid storage component 4, wherein the air delivery component 5 can press liquid in the liquid storage component 4 into the washing barrel 1 in a mode of delivering air into the liquid storage component 4, so that clothes in the washing barrel are soaked and penetrated by the liquid, and the liquid containing washing components (washing agents such as washing liquid dissolved in the liquid, washing powder and softener) can act on the surface and the inside of the clothes to remove stains attached to the surface of the clothes and immersed in the clothes. That is, the air delivery assembly 5 delivers air into the sealed liquid storage assembly 4 to increase the air pressure inside the liquid storage assembly 4, so that the air pressure inside the liquid storage assembly 4 is higher than the air pressure inside the washing tub 1, and the liquid inside the liquid storage assembly 4 is pressed into the washing tub 1 under the action of the air pressure difference, so as to wash the clothes inside the washing tub 1.
Since the washing tub of the washing apparatus is generally required to be communicated with a plurality of pipes such as a drain pipe set and a water inlet pipe set, it is obviously more difficult to reliably seal the washing tub 1 than to reliably seal the liquid storage assembly 4 and the gas transmission assembly 5, compared with a liquid inlet method of pumping gas from the inside of the washing tub 1 with reliable sealing to suck liquid into the washing tub 1. That is to say. In the same situation that the penetrating washing of the clothes in the washing tub 1 is realized, the sealing requirement of the above embodiment of the invention on the washing machine is lower, and the sealing reliability of the washing machine (the liquid storage assembly 4 and the air delivery assembly 5) is easier to be ensured.
As a specific embodiment, the wall of the washing tub 1 is provided with a first loading port 11 capable of communicating with the liquid storage assembly 4. The reservoir assembly 4 comprises a reservoir 41 for holding liquid and a first valve body 42 arranged between the reservoir 41 and the washing drum 1. The liquid storage tank 41 is provided with an opening allowing liquid to flow out, a passage allowing the liquid to flow into the washing tub 1 is formed between the opening and the first liquid inlet 11, and the first valve body 42 is arranged on the passage so as to open or close the passage, so that the liquid in the liquid storage tank 41 flows into the washing tub 1 through the passage when the liquid needs to enter the washing tub 1, and the passage is closed when the liquid does not need to enter the washing tub 1 so as to prevent the liquid from flowing out of the liquid storage tank 41. As shown in FIG. 1, the opening in the reservoir 41 may communicate directly with the first loading port 11 via the first valve body 42. Alternatively, in addition to the embodiment shown in fig. 1, the opening in the reservoir 41 may communicate with the first loading port 11 via a conduit in which the first valve body 42 is disposed. That is, the manner of disposing the passage between the reservoir 41 and the washing tub 1 is not limited.
As shown in fig. 1, the reservoir 41 is, as an example, at least one reservoir provided on an outer wall of the washing tub 1. The number of the liquid storage containers can be multiple (such as two), and the multiple liquid storage containers are communicated to form an integral liquid storage device. Or the number of the liquid storage containers is one, and the liquid storage container is a liquid storage device which is arranged around the outer wall of the washing barrel 1 and has an annular cross section. An opening for allowing the liquid to flow out is provided at the bottom of the tank 41 so that the bottom of the tank 41 communicates with the washing tub 1. The top of the tank 41 is provided with an opening for allowing gas to enter the interior of the tank 41, and the gas delivery module 5 communicates with the tank 41 through the top opening. Of course, the case that the liquid storage tank 41 is externally arranged on the washing tub 1 also includes the case that the liquid storage tank is arranged outside the washing tub 1, and the washing tub 1 is arranged inside the washing machine, that is, the specific arrangement mode of the liquid storage tank 41 can be set according to the actual requirement of the washing machine.
The air delivery assembly 5 comprises an air pump 51 and a first air inlet line 52. One end of the first air inlet pipeline 52 is hermetically connected to the air pump 51, and the other end of the first air inlet pipeline 52 is hermetically connected to the closed liquid storage tank 41, specifically, the top opening position of the liquid storage tank 41, so as to communicate the air pump 51 with the liquid storage tank 41. In case of a need to enter liquid in the washing tub, the first valve body 42 is opened, the washing tub 1 and the liquid storage tank 41 are in a communicated state, and a small amount of liquid in the liquid storage tank 41 slowly floods into the washing tub 1. At the same time, the air pump 51 operates to supply air into the liquid storage tank 41 through the first air inlet line 52, so that the air in the liquid storage tank 41 above the liquid level is rapidly increased, and the air pressure in the liquid storage tank 41 is increased. When the difference between the air pressure in the liquid storage tank 41 and the air pressure in the washing tub 1 increases to a certain degree, the liquid in the liquid storage tank 41 is sprayed into the washing tub 1 in a manner of being pressed into the washing tub 1 under the action of the air pressure difference, the speed of the liquid entering the washing tub 1 increases until the liquid completely enters the washing tub 1, and the washing of the clothes in the washing tub 1 is completed.
With continued reference to fig. 1, as a preferred embodiment, the liquid in the liquid storage assembly 4 enters the washing tub 1 by: a liquid channel is provided in the washing tub 1, and a liquid outlet 2111 (the liquid outlet 2111 will be described in detail later) is provided on the pulsator 2, and the liquid channel is configured to communicate the liquid storage assembly 4 with the liquid outlet 2111, so that the liquid in the liquid storage assembly 4 can be pressed into the washing tub through the liquid channel and the liquid outlet 2111. So that the liquid in the liquid storage assembly 4 can enter the washing barrel 1 above the impeller 2 through the liquid channel and the liquid outlet 2111. Through the arrangement, the liquid in the liquid storage assembly 4 can be pressed into the washing barrel through the path of the liquid storage assembly 4-the liquid channel-the liquid outlet 2111-the washing barrel 1, so that the liquid is sprayed upwards from the bottom of the clothes, the impact force of the sprayed liquid on the clothes is larger, the penetrating effect is better under the action of the gravity of the clothes, and the washing effect of the clothes is further optimized. Specifically, the first liquid inlet 11 is located below the pulsator 2. The liquid channel is arranged below the impeller 2 and is respectively communicated with the first liquid inlet 11 and the liquid outlet 2111 (the communication condition comprises that the liquid channel is provided with two openings, one of the two openings is communicated with the first liquid inlet 11, and the other opening is communicated with the liquid outlet 2111, or at least one of the first liquid inlet 11 and the liquid outlet 2111 is an opening directly formed on the liquid channel), so that water in the liquid storage assembly 4 can flow through the liquid channel and is sprayed out from the liquid outlet 2111 to the washing barrel 1 above the impeller 2 after entering the liquid channel through the first liquid inlet 11.
As a specific embodiment, the liquid channel may be specifically arranged in a manner that: according to the orientation of fig. 1, the pulsator 2 includes a body 21, a first partition 22 disposed below the body 21, and a second partition 23 disposed spaced below the first partition 22. Wherein, a plurality of convex ribs 211 are arranged on the body 21, and each convex rib 211 is provided with a liquid outlet 2111 inclined relative to the vertical direction; the first partition plate 22 and the second partition plate 23 are both circular annular plates, a cylindrical baffle plate 222 is arranged in the inner ring position of the first partition plate 22 along the vertical downward direction, and both ends of the baffle plate 222 are hermetically connected with the first partition plate 22 and the second partition plate 23, so that a sealed accommodating space is formed in the inner ring position of the first partition plate 22 and the second partition plate 23, and an adapter for connecting the impeller 2 and the driving element can pass through the accommodating space and then is connected with the body 21 (namely, the adapter is connected to the body 21 after passing through a cylindrical cavity in the middle of the baffle plate 222); the outer rings of the first partition 22 and the second partition 23 are each sealingly connected to the inner wall of the washing tub 1 by a sealing ring 25 to form a chamber between the first partition 22 and the second partition 23 which is capable of allowing the liquid to enter. And a plurality of second liquid inlets 221 are arranged on the first partition 22 in a penetrating manner, so that the chamber can be communicated with the liquid outlet 2111 on the main body 1. The first loading port 11 is located between the first partition 22 and the second partition 23 as another opening of the liquid passage. That is, the liquid channel comprises the first loading port 11, the chamber and the second loading port.
Under the condition that the liquid in the liquid storage assembly 4 is pressed into the washing tub 1, the liquid enters between the first partition plate 22 and the second partition plate 23 through the first liquid inlet 11, and is sprayed out of the body 21 through the second liquid inlet 221 and the liquid outlet 2111 on the first partition plate 22, so as to enter the washing tub 1 above the pulsator 2.

That is to say, under the condition that a plurality of liquid outlets 2111 with the same inclination direction are distributed on a plurality of ribs 211 of the impeller 2, the liquid can be obliquely sprayed from the impeller 2 to the washing tub 1 above the impeller 2, so that the impeller 2 can be pushed to rotate by the reaction force generated in the process of oblique spraying of the liquid, the liquid enters the washing tub 1 to wash the clothes, and simultaneously the impeller 2 can be driven to rotate, the impeller 2 can stir the clothes more powerfully under the condition that the washing machine does not consume excessive energy, and the washing performance of the washing machine is optimized.
As a preferred embodiment, the washing machine further comprises a rotating assembly 6 connected to the pulsator 2, and the air delivery assembly 5 is capable of driving the rotating assembly 6 to rotate in an air delivery manner, thereby rotating the pulsator 2. Specifically, a gas passage connected to the gas delivery unit 5 is provided in the washing tub 1, and the rotation unit 6 is provided in the gas passage. Gas delivery module 5 further includes a second inlet line 53 and a first outlet line 55. The gas passage includes a gas inlet 12 (the gas inlet 12 will be described in detail later) and a gas outlet 13 (the gas outlet 13 will be described in detail later), which can be communicated with the external environment, one end of a second gas inlet pipeline 53 is communicated with the gas pump 51, the other end of the second gas inlet pipeline 53 is communicated with the gas inlet 12, so that the gas output by the gas pump 51 can enter the gas passage along the second gas inlet pipeline 53 and the gas inlet 12, the gas outlet 13 is communicated with a first gas outlet pipeline 55, the first gas outlet pipeline 55 can guide the gas exhausted from the gas outlet 13 to the outside of the washing machine, after the gas enters the gas passage through the second gas inlet pipeline 53 and the gas inlet 12, the gas flows through the gas passage and is exhausted through the gas outlet 13 and the first gas outlet pipeline 55, so that the gas can form a gas flow capable of driving the rotating assembly 6 in the gas passage through the continuous gas inlet of the gas inlet 12 and the gas outlet of the gas outlet 13, make gas transmission subassembly 5 not only can be with the liquid of stock solution subassembly 4 impress in the washing tub 1, can also drive impeller 2 and rotate, thereby dynamics when having guaranteed impeller 2 and stirring the clothing, so that the clothing can be through between clothing and the impeller, the clothing is each other and the clothing is washed through the friction of each other between clothing and the wash water, make the clothing both constantly pierce through by liquid and wash and through above-mentioned friction by the washing, the washing effect of clothing has been promoted, the washing efficiency of clothing has been guaranteed.
As shown in fig. 1, in the case that the liquid passage is provided below the pulsator 2, the gas passage may be specifically provided in a manner of: according to the orientation of fig. 1, a third partition plate 24 is further disposed below the second partition plate 23 at the bottom of the pulsator 2, the third partition plate 24 is a circular plate disposed at a distance from the second partition plate 23, and sealing rings 25 seal between the outer edge of the circular plate and the inner wall of the washing tub 1 (the number of the sealing rings 25 is three, and the sealing rings 25 are sealed between each partition plate and the inner wall of the washing tub 1), so as to form a chamber capable of allowing gas to enter between the second partition plate 23 and the third partition plate 24. The gas inlet 12 and the gas outlet 13 are disposed on the left and right sides of the washing tub 1, and the gas inlet 12 and the gas outlet 13 are both disposed between the second partition 23 and the third partition 24, so that the chamber allowing the gas to enter can be communicated with the gas delivery assembly 5 through the gas inlet 12, and can be communicated with the external environment through the gas outlet 13, thereby forming the gas passage (i.e., the gas passage includes the chamber allowing the gas to enter and the gas inlet 12 and the gas outlet 13).
The rotating assembly 6 includes an impeller 61 disposed between the second partition 23 and the third partition 24, and a rotating shaft 62 (i.e., the above-described adaptor) that coaxially connects the impeller 61 with the body 21. One end of the rotation shaft 62 is connected to the rotation center of the impeller 61, and the other end of the rotation shaft 62 passes through the inner ring of the second partition plate 23 and the cylindrical accommodation cavity in the middle of the baffle 222 to be connected to the rotation center of the body 21. In this case, the washing machine further includes a bearing 63 and a bearing seal 64, wherein an inner race of the bearing 63 is closely fitted to the rotation shaft 62, and an outer race of the bearing 63 is closely abutted to an inner side surface of the middle of the baffle 222, thereby reliably supporting the rotation shaft 62 at the bottom of the pulsator 2, the second and third partition plates 23 and 24. The bearing seal 64 is sleeved on the rotating shaft 62 to cover the inner ring position of the first partition 22, so as to prevent the liquid from entering the baffle 222.
When the gas transmission assembly 5 transmits gas to the gas channel through the gas inlet 12, the gas output by the gas transmission assembly 5 is continuously discharged to the external environment through the flow path from the gas inlet 12 to the chamber between the second partition 23 and the third partition 24 to the gas outlet 13, so that a gas flow capable of pushing the impeller 61 to rotate is formed in the chamber between the second partition 23 and the third partition 24, and the rotating force generated when the impeller 61 rotates is transmitted to the body 21 through the rotating shaft 62, so as to drive the body 21 to rotate, thereby achieving the purpose of stirring clothes and liquid in the washing tub 1.
Preferably, one embodiment of the liquid flowing back from inside the washing tub 1 to the reservoir 41 is: the tank 41 is provided with an opening for allowing gas to be discharged, and the opening is provided with a second valve body 43 at a position where the second valve body 43 can open/close the opening to connect/disconnect the tank 41 to/from the external environment. When it is necessary to return the liquid to the liquid storage tank 41, the second valve body 43 is opened to communicate the liquid storage tank 41 with the external environment, and the gas in the liquid storage tank 41 overflows into the external environment until the pressure of the liquid storage tank 41 is reduced to be the same as that of the external environment. Since washing tub 1 is sealed by door 3 in the washing state and the drain line connected to washing tub 1 is in the closed state, washing tub 1 is in the closed state at this time. When the liquid is pressed into the washing tub 1, the increased liquid compresses the air above the liquid level in the washing tub 1, so that the air pressure in the washing tub 1 is increased, the air pressure in the washing tub 1 is higher than the air pressure in the liquid storage tank 41 at the moment, the liquid in the washing tub 1 is pressed back into the liquid storage tank 41 under the action of the air pressure difference until the liquid flows back into the liquid storage tank 41, and the liquid completes one cycle between the washing tub 1 and the liquid storage tank 41. The circulation of liquid is repeated until the washing process of the washing machine is completed, so that the laundry in the washing tub 1 is thoroughly cleaned.
Referring to fig. 2, fig. 2 is a second structural view of the washing apparatus of the present invention, in which a structure of the washing apparatus capable of discharging liquid from the washing tub is shown. As shown in fig. 2, the washing machine of the present invention preferably has a drainage mode: a water outlet 14 is provided at the upper part of the washing tub 1, a drainage pipeline 15 is connected to the water outlet 14, the liquid in the washing tub 1 can be drained to the outside of the tub through the water outlet 14, and the drainage pipeline 15 can guide the liquid flowing out from the water outlet 14 to the outside of the washing machine. The pulsator 2 is disposed in the washing tub 1 in a liftable manner. The air delivery assembly 5 can raise the impeller 2 in an air delivery manner, so that clothes above the impeller 2 and liquid are lifted upwards by the impeller 2, and the liquid level of the liquid is raised continuously until the liquid level rises to the height of the water outlet 14, so that the liquid is discharged from the water outlet 14. As the pulsator 2 continues to ascend to a position close to the drain port 14, substantially all of the liquid in the washing tub 1 is discharged to the outside of the washing tub 1, and the draining process of the washing machine is finished.
Specifically, the pulsator 2 (including a body 21 and first, second, and third partitions 22, 23, and 24 disposed below the body 21) is disposed inside the washing tub 1 in a piston fashion along the axial direction of the washing tub 1. And a certain distance is arranged between the impeller 2 and the bottom of the washing barrel 1, so that an accommodating cavity with variable volume can be formed below the impeller 2. The gas transmission assembly 5 further comprises a second gas outlet pipeline 56, one end of the second gas outlet pipeline 56 is communicated with the first gas outlet pipeline 55, and the other end is communicated with the bottom of the washing barrel 1 and is communicated with the accommodating cavity with variable volume. And a third valve body capable of closing/opening the first intake pipe 52 is provided on the first intake pipe 52. The first air outlet pipeline 55 is provided with a fourth valve body 57 capable of closing/opening the first air outlet pipeline 55, and the fourth valve body 57 is arranged behind the communication position of the second air outlet pipeline 56 and the first air outlet pipeline 55, namely when the fourth valve body 57 is closed, the first air outlet pipeline 55 still can form a passage with the opening of the second air outlet pipeline 56 between the air outlet 13 and the accommodating cavity, but the tail end of the first air outlet pipeline 55 is not communicated with the external environment.
In this situation, when the washing machine is in the drainage condition, the drainage pipeline 15 of the washing machine is opened, the first valve body 42, the second valve body 43, the third valve body 54 and the fourth valve body 57 of the washing machine are all in the closed state, the air delivery assembly 5 and the liquid storage tank 41 are not communicated, and the first air outlet pipeline 55 is in the closed state where the air cannot be discharged. At this time, the air pump 51 is operated, and the air output by the air pump 51 enters the air channel between the second partition 23 and the third partition 24 along the second air inlet pipeline 53 and the air inlet 12, and enters the accommodating cavity at the bottom of the washing tub 1 along the flow path of the air outlet 13, the first air outlet pipeline 55 and the second air outlet pipeline 56 after flowing through the air channel, so that the air in the accommodating cavity is increased, the volume of the accommodating cavity is increased, and the impeller 2 is continuously lifted upwards by the increased air in the accommodating cavity below the impeller; when the impeller 2 is lifted above the air inlet 12 and the air outlet 13 by the increasing air in the accommodating cavity, the air passage between the air inlet 12 and the air outlet 13 is cut off, and the third partition plate 24 rises above the air inlet 12 and the air outlet 13 (the thickness of the third partition plate 24 can be smaller than the maximum radial dimension of the air inlet 12 and the air outlet 13 so as to avoid the third partition plate 24 from blocking the air inlet 12 and the air outlet 13 during the lifting process). At this time, the air output by the air pump 51 directly enters the containing cavity in the washing tub 1 and below the pulsator 2 through the second air inlet pipeline 53 and the air inlet 12 (or after a part of the air overflows from the air outlet 13, returns to the containing cavity again along the flow path of the air outlet 13, the first air outlet pipeline 55 and the second air outlet pipeline 56), so that the air in the containing cavity continuously increases to lift the pulsator 2 upwards continuously to raise the liquid level of the liquid above the pulsator 2, and the liquid above the pulsator 2 is discharged through the water outlet 14 in the upper part of the washing tub 1 until the pulsator 2 is lifted to a position close to the water outlet 14, the body 21 and the water outlet 14 are approximately flush, at this time, the liquid above the pulsator 2 is substantially completely discharged, and the water discharging process is finished.
Of course, while the above-described drainage process includes two different gas delivery paths, this is not limiting. For example, the air transmission pipeline can be directly communicated between the accommodating cavity and the air pump 51, so that the air pump 51 can directly input air into the accommodating cavity without inputting air into the accommodating cavity through the air channel when air transmission is started. That is, the gas transmission path can be specifically set according to the actual design requirement, as long as the normal gas entering into the accommodating cavity is not affected.
Furthermore, the dehydration mode of the washing machine is as follows: the washing machine further comprises a dehydration pressure plate 31, and the dehydration pressure plate 31 is arranged below the door body 3 in a fixed connection or integrated forming mode. After the liquid above the pulsator 2 is substantially discharged to the outside of the washing tub 1, the pulsator 2 is located at an upper portion of the washing tub 1, and the laundry in the washing tub 1 is located between the body 21 of the pulsator 2 and the dehydration platen 31. In this case, the open state of the drain line 15 and the closed states of the first valve body 42, the second valve body 43, the third valve body 54, and the fourth valve body 57 are continuously maintained, and the air pump 51 continues to supply air into the accommodating chamber in the washing tub 1, so that the pulsator 2 continues to ascend. At this time, the laundry is lifted up to the spinning platen 31 by the pulsator 2. And as the pulsator 2 continuously ascends, the laundry is pressed by the dehydration pressure plate 31 and the body 21, the liquid in the laundry is pressed into the washing tub 1 and discharged to the outside of the washing tub 1 through the drain port 14 and the drain line 15, until the liquid in the laundry is substantially completely pressed out, and the dehydration process of the laundry is finished.
After the drainage and dehydration processes of the washing machine are all finished, the air pump 51 stops working, the fourth valve body 57 is opened, the first air outlet pipeline 55 is opened, and the accommodating cavity is communicated with the external environment through the air outlet 13 and the first air outlet pipeline 55. Under the action of gravity of the pulsator 2 and the clothes above the pulsator 2, the gas in the containing chamber is discharged to the outside of the washing tub 1 through the gas outlet 13 and the first and second gas outlet pipes 55 and 56 in such a manner as to be pressed downward by the descending pulsator 2, and the pulsator 2 returns to the bottom of the washing tub 1. At this time, the user can open the door 3 to take the laundry out of the washing tub 1.
Of course, after the drainage and dehydration processes of the washing machine are all finished, the impeller 2 can be stably stopped at the upper part of the washing machine after the door body 3 is opened by firstly releasing a small amount of gas or adding a protective structure at the top of the washing tub, so that the impeller 2 can descend after the user finishes taking the clothes, and the user can take the clothes out of the washing tub 1 without bending down.
In summary, the washing machine of the present invention comprises a washing tub 1, a pulsator 2 rotatably disposed in the washing tub 1, a liquid storage assembly 4, and an air delivery assembly 5 communicated with the liquid storage assembly 4. Wherein, the impeller 2 is provided with a liquid outlet 2111 slantingly and a liquid channel and a gas channel are arranged below the impeller 2, the liquid storage component 4 is communicated with the washing barrel 1 through the liquid channel, the gas transmission component 5 is also communicated with the gas channel, and the rotating component 6 coaxially connected with the impeller 2 is arranged in the gas channel. The air delivery assembly 5 can obliquely spray the liquid in the liquid storage assembly 4 out of the impeller 2 in a manner of delivering air into the liquid storage assembly 4, so that the liquid is pressed into the washing barrel 1 and the impeller 2 is driven to rotate by the reaction force generated when the liquid is sprayed. And the gas transmission component 5 also drives the rotating component 6 to rotate by means of gas transmission into the gas channel, so as to drive the impeller 2 to rotate. Through the arrangement, on the one hand, the washing machine can realize the liquid inlet operation of the washing barrel 1 only by sealing the gas transmission assembly 5 and the liquid storage assembly 4, and the sealing requirement of the washing machine is reduced. On the other hand, the washing machine of the invention can realize the liquid inlet of the washing barrel 1 and the driving of the impeller 2 at the same time only by one group of air transmission assemblies 5, and can stir the clothes in the washing barrel 1 powerfully by the impeller 2 when the clothes are repeatedly penetrated by the liquid for washing, thereby improving the washing effect of the clothes.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
